Description

TECHNICAL FIELD

This invention relates to a decking clip and a decking assembly comprising such a clip. More specifically, the present invention related to a clip for the spacing and retention of extruded metal decking panels.

BACKGROUND OF THE INVENTION

Exterior ground surfaces, such as decking or paving, are popular in a variety of different settings. In general, a plurality of support joists, which may or may not be arranged in a lattice, are secured to pedestals, cradles, i-beams or other structures which directly contact the ground surface.
Decking and other exterior flooring systems for balconies and terraces are sometimes prefabricated for many reasons, e.g. cost, efficiency and speed of installation. Metal is a hard material that has a tendency to rattle when two components (such as decking panels) are positioned adjacent to each other. When implementing a metal decking system, it is desirable to try and eliminate any rattling in use.
Further, it is also desirable to prevent any loosening of fasteners.
Also, it is desirable to provide a system where individual decking panels can be removed and replaced in case of e.g. damage. Also, it is advantageous to have some boards that are easily removeable to allow access to lifting points to allow access to e.g. lifting points for decked balconies that need to be lifted into place.
The present application aims to address some of the above-mentioned issues.

DETAILED DESCRIPTION

Referring to FIGS. 1 and 2 , a decking clip 100 is provided. The clip 100 is a unitary component which in this case is constructed from an extruded aluminium material. The clip 100 is generally prismatic, having a constant cross-sectional profile (except for an opening, which will be described below). For the purposes of this description, the clip 100 has a longitudinal direction X along its prism axis, a transverse, horizontal direction Y and a vertical direction Z.
The profile of the clip 100 comprises a base 102 and an upright 104.
The base 102 is generally flat and planar having a first edge 105 and a second edge 106, a first, upper surface 108 and a second, lower surface 110. The base 102 has two feet 112, 114 each running in the longitudinal direction X. The first foot 112 is proximate the first edge 105, and the second foot 114 proximate the second edge 106. The feet therefore define a raised portion 116 therebetween.
The base 102 defines a fastener opening 118 in the centre thereof, positioned between the feet 112, 114. The opening passes through the thickness of the base 102 and is coincident with the raised portion 116.
The upright 104 defines a profile having a first, lower end 120 attached to the base 102 on the upper surface 108 of the base. The first end 120 is positioned inboard of the first foot 112 such that it is positioned above the raised portion 116. The upright has and a second, free end 122 distal to the base 102. The upright is of generally constant thickness but has a curved profile as will be described below.
The profile of the upright 104, starting from the first end 120 has a first curved portion 124 extending towards the first edge 104. The first curved portion 124 is generally S-shaped such that the profile of the upright 104 moves towards and over the first foot 112 where it joins a straight section 126. The straight section 126 extends in the vertical or X direction to a second curved portion 128 which is semi-circular in form. The second curved portion terminates in the second, free end 122 that faces the base 102 and is positioned vertically above the lower end 120 of the upright 104. As such, the upright 104 defines an elongate ‘C’ shape facing from proximate the first edge 104 in the direction of the second edge 106—i.e. in the direction of the opening 118.
Referring to FIG. 1 , the upright 104 is shown as vertical (aligned with the Z axis). The base 102 on the other hand is angled upwards from the Y axis by θ degrees, such that the upright 104 and base 102 form an angle of less than 90 degrees-specifically 90-θ degrees.
The outer surface of the decking clip is coated in a coating material 103. The coating material (in this case paint) is less stiff than the material from which the clip is constructed. It is elastically deformable, and resiliently compressible.
Turning to FIG. 3 , the clip 100 is shown in a first stage of installation. An extruded aluminium decking panel 202 is prismatic in shape. The cross-sectional profile of the panel 202 is shown partially in FIG. 3 . It will be noted that the decking panel 202 is generally symmetrical having a similar profile on the other side in the Y direction. Each panel has a flat, substantially planar deck 204. The deck 204 has a plurality of longitudinally extending grooves 206 defined therein to enhance grip and drainage.
The panel profile defines a leg 208 extending downwardly from the deck 204. Leg 208 is defined at the edge of the profile. The leg 208 at the free end (opposite the deck 204) defines an inwardly projecting first foot portion 216. The foot portion 216 is a flange extending from the free end of the leg. Extending outwardly from the leg 208 partway up, there is provided a flange 220 forming a shoulder at 90 degrees to the leg, which terminates in a downwardly depending toe portion 224.
At the edge of the deck profile a downwardly depending end flange 236 is provided. The end flange 236 is aligned with (i.e. vertically above) the toe portion 224. The end flange 236 is spaced apart from the leg 208 to define a pocket 237.
The clip 100 is assembled with the panel 202 by hooking the curved portion 128 into the pocket 237. The clip 100 is then rotated in a direction D until the first edge 105 abuts the outer side of the leg 208, and the foot 112 abuts the top surface of the flange 220 forming a shoulder. It will be noted that the height of the clip V (FIG. 1 ) is similar to the vertical distance A between the upper surface of the flange 220 and the upper inner surface of the pocket 237. The coating of the clip 100, needs to be elastically deformed in order to fit it into the deck profile.
The top of the clip 100 (i.e. the uppermost extend of the upright 104) is positioned horizontally inboard of the first foot 112. This means that the reaction forces F1 (from the pocket, downwardly on the clip) and F2 (from the foot upwardly on the clip) form a torque T in a direction configured to retain the clip 100 in the decking panel. This enables the clip 100 to be held in position as the panel 202 is put into place.
Referring to FIG. 4 , the next step of installation is shown in which a further decking panel 202′, identical to the first is installed adjacent thereto. Whereas the right-hand side of the panel 202 is shown in FIGS. 3 and 4 , the mirror-image left-hand side of the panel 202′ is shown in FIG. 4 . The panel 202′ is moved towards the panel 202 such that the second edge 106 of the clip base 102 sits above the flange 220′ of the panel 202′, adjacent the leg 208′. It will be noted that because the base 102 is at an angle of 90-θ degrees to the upright, which is held snugly in the pocket 237, the base 102 sits above the flange 220′, not in contact therewith. In other words there is a gap between the flange 220′ and base 102 (or specifically the foot 114). This is beneficial because it allows the decking panel 202′ to be slid into position adjacent the decking panel 202 without the clips hitting the side of the panel 202′.
Once the panel 202′ is in position—i.e. once the base 102 abuts the leg 208′, a fastener (in this case a screw 300) is passed through the opening 118 of the clip 100 to be engaged with an underlying substrate 302. As the fastener 300 is tightened, the base 102 of the clip 100 is drawn downwards, applying a torque T2, elastically deforming the clip 100 until the foot 114 abuts the flange 220′. The raised portion 116 is also drawn downwards in bending as the fastener 300 is tightened.
It will be noted that the upright 104 is constructed with a lower thickness than the base 102. This coupled with the fact that the upright 104 is curved in profile enables it to act as a spring to permit rotation of the base 102 relative thereto. By tightening the fastener, the clip 100 is “opened out”, increasing the angle between the base 102 and upright 104 to 90 degrees.
Once tightened, the fastener 300 is placed in tension due to the elastic deformation of the clip 100. This mitigates loosening and vibration/rattling. Further, both panels 202, 202′ are clamped by the clip 100 thus reducing movement and therefore vibration/rattling.
It will be noted that multiple clips 100 are provided per panel 202 to secure it to the substrate 302 and adjacent panel 202′. Further such panels may also be assembled in a similar manner to form a decking assembly.

VARIATIONS

The clip 100 may be constructed from other materials. It may be constructed from other metal materials, such as steel or plastics materials, although it will be noted that plastics may be less desirable in certain applications dues to their reduced fire resistance.
The clip may be manufactured in a number of ways, including extrusion and moulding.
